Drainback Solar Water Heater System from China
A drainback solar water heater system that uses distilled water and automatically drains collectors when the pump stops to prevent freezing. Despite the minimal pump for circulation, it is classified as a non-electric solar water heater under tariff item 8419.12.00 because the heating function is entirely solar-driven and the pump is auxiliary.
